A specific extract from the root of the American ginseng plant protects brain connections and improves memory in aged rats. Researchers found that this botanical supplement boosts the brain’s natural cellular waste disposal system, helping neurons survive the physical stresses of aging. The study was published in the journal Alzheimer’s & Dementia.
As organisms get older, their cells gradually lose the ability to clean up damaged or misfolded proteins. This biological decline is particularly problematic in the brain, where cells must last an entire lifetime. Neurons rely heavily on a microscopic waste management system to maintain their structural integrity and process information without disruption. The consistent removal of older proteins prevents cellular blockages and allows the brain to replace worn-out components with working parts.
At the center of this cellular cleanup effort are organelles called lysosomes. These tiny, membrane-bound structures act as living recycling centers. They swallow unwanted cellular debris and use a mixture of specialized acidic enzymes to break down old proteins into their basic building blocks…
